Skills Covered

  • Tell a question data can answer from one with a single answer
  • Choose a survey, observation, measurement or experiment
  • Tally data into a frequency table with a title and labels
  • Read frequency tables of fractions and decimals
  • Make stem-and-leaf plots with a key
  • Find the mode, median and range of a data set

How to Use This Pack

Five pages that follow data from the question to the answer. Page 1 has students circle the question that needs data in each pair, check whether a survey, an observation, a measurement or an experiment would collect the data for seven questions, and write a question of their own. Page 2 counts the letters in 24 first names and tallies them into a frequency table, with its title and the first column's label to write, then makes a whole table from the goals a team scored in 16 games; one- and two-step questions follow each table. Page 3 tallies earthworm lengths in quarter inches and reads a table of running times in tenths of a second, with questions such as how much longer the longest earthworm is than the shortest. Page 4 makes stem-and-leaf plots with the leaves in order, a title and a key, after a worked example, then rewrites a plot whose leaves were written down out of order. Page 5 reads a stem-and-leaf plot of points scored (least, greatest, range, mode, median and two more questions), then finds the mode, median and range from two frequency tables, one with fractions.

In the Classroom

Start with page 1 as a class: read each pair of questions aloud and ask whether everyone would give the same answer. Then have each table group count the letters in their own first names and add them to a class frequency table on the board before page 2. For page 4, write a few two-digit numbers on sticky notes and sort them into rows by their tens digit to show where the stems come from.

At Home

Count something together for a week, such as the minutes spent reading each day or the cars that pass during dinner, and keep a tally. At the end, ask your child to make a frequency table and tell you the most common value and the range.

Tips for Success

  • A question needs data when people would give different answers
  • Cross off each piece of data as you tally it, so none is counted twice
  • The frequencies in a table should add up to the number of pieces of data
  • In a stem-and-leaf plot, the stem is the tens digit and the leaf is the ones digit; write the leaves in order
  • To find the median in a frequency table, count through the rows to the middle value

Frequency Tables and Stem-and-Leaf Plots

4th Grade

Collecting data and showing it in frequency tables and stem-and-leaf plots, from the question to the mode, median and range. Students plan how to collect data, tally whole numbers, fractions and decimals into titled tables, make and read stem-and-leaf plots, and answer one- and two-step questions.
